Question

Pre-Lab Study Questions Name Electronic Structure of the Atom and Flame Tests 1. Why do metal-containing ions produce glowing colors when heated in flames? 2. Why is it that different metal ions produce different colors in flames? 3. It is necessary to clean the testing wire each time a sample is changed. Give a reason for this. 4. Write down the electron configuration of Na 5. Write down the electron configuration of Na

Answer 1

when metal containing is heated it absanbs heat eneagy and electaons geis excited to highex energy levet and electaon then OF cextain wavelength theaefore praduces calours elease enengy 2 Because evesy metal ton has different binding energy with nucleus So it excited at different enengy and also ae lease the different wavelength when it comes do ground State they Show different colaurs 3. Because, somne ions may be adhere the testing wire of it daes nat aet cleax flame test of a curarent sample Previaus sample herel Sodium CNa has atomic na 11 TH's electaonic configunation is Nacu - Is22522p6 as when sadium loosel ohe electaoo then it foxms F.C hecomes is2s22 p 5.
